摘要
在塔塔尔斯基理论模式下,使用全国81个探空气象站1986-1995年10年探空资料计算了各测站不同高度上的Fried参数r0,统计结果表明,r0年平均值存在明显的地理分布,高值中心在3000 m高度上是夏河合作、丽江和上海;在1500 m高度上为民勤和贵阳,在900 m高度上为汉中;在测站海拔高度上为定日,r0的月平均值的地理分布存在显著的季节变化,这种变化与东亚副热带急流季节性变化相吻合.
Using sounding data in the years 1986-1995, the Fried parameter r0 with different height are calculated by means of the theoretical model of Tatarski over 81 radiosonde stations in China. The statistical results show that the annual mean r0 is depending on geographical distribution evidently, and the peak of r0 occurs in Xiahe Hezuo ,Lijiang and shanghai at the height of 3000m ,in Minqin and Guiyang at the height of 1500 m,in Hanzhong at height of 900 m and in Dingri at the height of stations above sea level and that the seasonal migration of the geographical distribution of the monthly mean r0 is apparent and which correspond with the seasonal behaviour of the subtropical jet stream.
